Three witnesses, including the No. 2 diplomat in Libya during the Benghazi attack, testified before Congress last week. Comments from Facebook:

The same people jumping on the Obama administration right now are probably, by and large, the same folks who defended the Bush administration during its failures over Iraq. Forget the stupid political posturing. Let us focus on identifying and fixing the problem.

— Hugh Marshall

Political posturing? Who was posturing right after our Americans were killed? Who was covering up mistakes and lying about it just before an election? Who has failed to even fix the problem eight months later?

People are sick of retorts bringing up George W. Bush. Now, what Bush did was "a long time ago," to borrow a phrase White House spokesman Jay Carney used recently when speaking about Benghazi.

— Mark Jones

The American public needs to know whom to blame for not providing protection for Ambassador Christopher Stevens, whom to blame for refusing Stevens' call for help, and whom to blame for deceiving the American public about the Benghazi attack over the last eight months. Part of the goal of congressional oversight is to find blame for incompetence and to hold whoever is responsible accountable.

Clearly, President Obama and Hillary Clinton are refusing to accept responsibility and are making it difficult for the whistle-blowers to come forward.

— James VanTrees

Let's not get it twisted; the crime is in the coverup. If the administration would have just admitted that it dropped the ball, we would not even be talking about this.

— Michael Kays

Republicans are out there misleading and rallying people because they know if Hillary Clinton runs for president in 2016, there will be no one who can beat her.

— Dorothy Herman

Why aren't we spending as much time investigating the Texas fertilizer plant explosion? Far more lives were taken and ruined there.

— Jeff Bohren

Letters to the editor:

Congress is at last attempting to get at the truth of what happened, and what didn't happen the day that four U.S. citizens, including Ambassador Christopher Stevens, were killed. No help was given, and personnel in a position to go to their aid reportedly were told to stand down.

But the real problem is why did the president and others speak of a video causing this attack and call it a spontaneous outbreak of violence when it was shown clearly to be an organized attack on Americans? And what is the administration so fearing will happen?

Instead of real reporting on this issue, we get news coverage of Jodi Arias, who was just convicted of murder. Now, it is an interesting case, but not really something that needs such widespread national coverage.

Every Democrat in America should be embarrassed by the actions of the Democrats in the hearings on Benghazi last week. Disgraceful behavior.

The three witnesses were giving their honest answers to questions, and all the Democrats seemed to do was try to protect Hillary Clinton and President Obama.
